rasterbaserade
Rasterbaserade (from Swedish raster-based) describes systems, images and data models that represent information as a regular grid of discrete cells or pixels. Each cell stores a value or set of values that represent properties at that location, such as color, elevation, temperature, or reflectance. Raster-based approaches contrast with vector models, which represent features using points, lines and polygons.
Raster data are common in digital photography, remote sensing, geographic information systems (GIS), scientific imaging and
Advantages of raster-based representations include simplicity of analysis, natural fit for continuous phenomena and efficiency for
Processing workflows for raster-based data include resampling, reprojection, compression, segmentation and change detection. In GIS and
